# All the steps required to get this simple plot: | |
# 1) Install VM VirtualBox on my windows machine | |
# 2) Download LinuxMixt (LMDE4) .iso | |
# 3) Create new VM for Linux Ubuntu and load .iso into the virtual optical drive | |
# 4) Startup the VM and click on "install" icon on the desktop (follow propmts) | |
# 5) Once finished with the basic install we need to enable "Guest Additions" to share clipboard/resize screen (all the goodies) VM->Devices->"Install Guest Additions CD Image" and run that | |
# 6) Install gvim (WTF!!) "sudo apt install vim-gtk3" | |
# 7) Get Python working with the correct libraries | |
# sudo su |
